This study documents long‐term changes in Common Guillemot Uria aalge chick diet on Skomer Island, Wales, from 1973 to 2017. Chick diet has remained broadly similar (mainly Clupeids) since 1973, although more recently there has been an increase in relatively low‐quality prey (Gadids), suggesting a shift in prey availability.
